Review of influence factors of natural gas hydrate formation and growth
摘要
Abstract
Natural gas hydrate is a kind of complex clathrate crystal formed by water and natural gas molecules,which has an important significance for research and utilization in industries of oil/gas pipeline transportation,natural gas storage and refrigeration. While the formation and growth of natural gas hydrate is a complex process involving multi-components and multistages,and the influence of different factors on hydrate formation and growth still needs to be understood. This paper introduces the physical process of natural gas formation and three hypotheses of natural gas nucleation. Then,the influences of substrate amphipathy,additives,porous media environment and impurities,liquid composition,temperature,pressure and flow conditions on hydrate formation and growth are discussed. At last,this paper points out that quantification of inhibition of hydrate caused by different crude oil compositions,influence of wax on mass transfer and heat transfer during hydrate growth,and a microscopic mechanism of kinetic hydrate inhibition should be further studied in the future.关键词
